Ok, I am probably being quite slow here, but I was trying to get everyone in my faction training more- so was working out percentage increase on stats,

but I found that in two weeks, people with around 30k stats had 14% increase- (on even stats, trained evenly- no drugs)

compared to someone with around 200k stats who had a 6-7% increase with training their main stat and using drugs.

If the stats increase exponentially why is it not reflective in the percentage increase?

Higher stats gain more stats but a lower percentage of your stats??

(I'm not a big maths person)

This is because the formula is:
(0.0002*STATS)+(0.00212*HAPPY+(0.55)) (and similar for defence)
^ the part based on your current stat is a part of the formula, but happy still plays a big role.
So, especially if everyone has similar housing, people will be gaining the same stats + a boost from existing stats. So % gained will always be a bit higher for lower stat players.

Make sense?

Yer, thanks- I realised, after working it out for a couple of players, the happy part played a large percentage in stat gain for v low players.

Ty for reply.
